Check engine ligths comes in. if battery is disconected it will stay off for a couple days before coming in again

You have a problem with the emissions system. Have the ECU scanned at almost any Auto Parts store. The code it retrieves will tell you what part is being effected. Not necessarily the defective part but what is being effected.

Service engine soon stay on the ligth?

Service engine soon is telling you to check computer for trouble codes. You can sometimes disconnect battery for 10 seconds and codes will erase. It is a good idea to have them checked. Most Auto stores like Autozone will check for free. You may have to call around. Most repair shops will charge $40 to check.

Service engine light stays on

the check engine ligth just means you are not passing emissions right now. Coud be due to loose fill cap at some time, or filling the tank with the key on.
Try disconnecting the battery ground cable for an hour. Then reconnect and drive for 10 miles until computer relearns engine changes. It may run rough for 10 miles.

If still on, go to Autozone and ask them to perform a free computer scan & get the fault code. It will tell you which sysem to check.

Check engine light on after overfill the tank. Check for codes at autozone, Change gas cap. Erase code. Ligth back on. Again to autozone. They say it is the gas cap. I let them know i have just replaced it...

You have a leak in the fuel system somewhere or a bad evaporative system sensor, the way the system works is the control module for the emission system pulls a vacuum on the gas tank and lines to check for leaks, if it can't get a certain vacuum level for a specified time it decides there is a leak and the check engine light comes on. This may be covered under the Federal Emissions warranty, call the dealer and inquire if the Evap System is covered.
